Installation as evaporator
For refrigeration applications – figure A below
shows the installation of an evaporator, for which
the connections may be either on the front or on
the rear. In evaporator applications and in applica-
tions in which a phase change of media occurs,
the heat exchanger should be installed vertically.
Figure B shows a condenser.
• Use an anti-freeze thermostat and flow monitor
to ensure a constant water flow before, during
and after the compressor has been running.
• Avoid “pump-down”, i.e. emptying the evapora-
tor by running the compressor after shut-down
until a preset refrigerant pressure is reached.
The temperature could then drop below the
brine freezing point, which could damage the
evaporator.
• Use a flow switch and a low-pressure switch.
Installation, welding aspects
For installation of AlfaNova equipped with welding
connections, TIG or MIG welding method must be
used for installation of the heat exchanger to min-
imize heat impact of the heat exchanger.

Note!
To avoid damage due to freezing, the
medium used must include an anti-
freeze agent at operating conditions be-
low 5 °C/41 °F and/or when the evapo-
rating temperature is below 1 °C/34 °F.
Note!
Protect the heat exchanger by using a
heat-sink (welding paste or tape) around
the connection before welding opera-
tion.
